説明

Staurosporine is a potent inhibitor of protein kinase C. To identify the genes that functionally interact with the Pkc1 pathway of the yeast Saccharomyces cerevisiae, we screened for the genes that cause induced staurosporine sensitivity when overexpressed from a galactose-inducible promoter. The novel gene ISR1 encodes a predicted protein kinase with the highest sequence similarity to mammalian Raf in the kinase domain. Drug sensitivity induced by ISR1 overexpression is specific to staurosporine. Although ISR1 disruption causes no obvious phenotype, it does exacerbate the phenotypes of a temperature-sensitive allele (stt1-1) of PKC1, but not of the mpk1 and bck1 mutants of the Mpk1 MAP kinase pathway. These results suggest that Isr1 functions in an event important for growth in a manner redundant with a Mpk1-independent branch of the Pkc1 signalling pathways.<br>
